I am looking for your opinions on this. I'm replacing the pt oil pan gasket it seeps a little so I am going to fix that. My question is gasket or rtv gasket maker? The rtv would be cheaper and a lot of news cars use that for a gasket for pans and timing covers ect vs a traditional gasket. What do you guys think is better ?
A gasket vs rtv

I'd use whatever the factory used. If it was a gasket, get a gasket. If it was silicone from the factory, then use that.

IF you clean the surfaces meticulously, and use grease on both sides of the gasket, you can get a good leak tight seal AND have ease of disassembly if you have any reason to go back into it in the future; assuming you use a gasket. I have a machinist friend who has done this for years on everything from his dirt bike to his 1973 Pontiac Trans Am, and he has never had leaks. I started doing it also.
I personally find RTV to be messy and avoid the use of it whenever possible. So if the factory used a gasket, then I would be using the OE gasket in that application.
I also try to use what the factory uses. If it was a gasket, I only use RTV if I can't get a good seal with a good gasket and after a try with re-torquing the bolts first. RTV can be more difficult to remove than a gasket if you ever need to again.
According to Rock Auto, the Fel-Pro OS30728R fits your ride. I followed Fel-Pro's instructions to the letter with success. Different application, same product line. The PermaDry technology is worth every penny.

A gasket usually only needs the correct torque values and the correct torque sequence.
RTV needs all that plus a uniform bead width and all kinds of other precautions.

The issue with RTV on an oil pan is that the factory puts it on before oil ever goes in the motor. You're on your back, and even after draining overnight, oil still oozes down the inside of your block and surface-tensions itself to your formerly clean surface flange.
I'd use one of those trick anaerobic sealers that cures in 15 minutes or that felpro product. I used a felpro valve cover gasket for saturn s series that replaced RTV with success-- because it was more "spongy" in its 3rd dimension than RTV could ever be it sealed better.

Not entirely true. Any gasket really needs the same things that an RTV sealant will need- CLEAN, dry, flat surfaces and minimum shifting during assembly and torquing.
Personally I find good RTVs to be as good or better than gaskets for many applications.

The quip about factories assembling before oil is mostly correct, but a good mechanic can do the same. When assemble parts for either a gasket or RTV, the same level of detail and attention is given. Never any leaks with either.

Who you tellin' about CLEAN, dry, flat surfaces ? You oughtta see what kind of mechanic I am. I make brain surgeons look like filthy hacks.
